想知道非cond1怎么写

cond1 =aa0>aa1 And aa0>aa2 And aa1>0 And aa2>0;//多均线入场    
  cond2 =aa1>aa0 And aa1>aa2 And aa0>0 And aa2>0;    
  cond3 =aa2>aa1 And aa2>aa0 And aa0>0 And aa1>0;

     cond4 =aa0<aa1 And aa0<aa2 And aa1<0 And aa2<0;//空均线入场    
  cond5 =aa1<aa0 And aa1<aa2 And aa0<0 And aa2<0;    
  cond6 =aa2<aa1 And aa2<aa0 And aa0<0 And aa1<0;
  
  
  cond7 =非cond1；

这个非怎么表示？
